This invention relates to ignition systems for internal combustion engines and more particularly to the distributor and ,coil thereof and has for the primary ohyect, the provision of means whereby the coil may form a cap or closure for the distributor adding to the compactness oi the device and permitting the electrical connections between the distributor and coil to be shortened and completely protected against moisture or.water, thus obviating short circuits and loss of electrical energy by the use of exceedingly long electrical conductors exposed to atmospheric conditions With this and other objects in view, this invention consists in certain novel features of construction combination and arran ement of parts to be hereinafter more in ly described and claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating a combined distributor and coil constructed in accordance with our invention and electrically connected to spark plugs,

Figure 2 is a vertical sectional view illustrating the same.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a vertical sectional view taken on the line 4-4 of Figure 3.

. Figure 5 is a detail sectional view illustrating the connection of a spark plug conductor to the distributor Figure 6 is a diagrammatical view illustrating the wiring diagram between the coil and distributor and the electrical source.

Referring in detail to the drawings, the numeral 1' indicates a distributor base in which is located the breaker assembly-2 including the usual rotor 3. A hollow body 4 of insulated material is removably mounted 5 on the base 1 and has operating therein the rotor 3. The base 1 overlaps the body 4toestablish a moisture-proof connection between said parts. The uppefend of the body is closed by a coil 5 the latter having a flanged portion overlapping a portion of the body to establish a moisture-prool connection between the coil and body. The coil 5 includes the usual primary and secondary windings with one terminal of the secondary winding connected to a yieldable brush or terminal 6 extending into the body 4 to engage the rotor 3. Vertically arranged barrels T formed integrally with the walls of body and have located therein conductor sleeves 8 the lower ends of which receive terminal posts 9. @ne of the posts 9 is connected to a ground as shown in Figure 6 and the other terminal 9 is electrically connected to the breaker assembly, the latter being electrically connected to a battery or electrical source 10 whichis connected by a conductor ll to the ground. The coil 5 has a ground conductor 12 to which the secondary and primary windings are connected and the conductor 12 is provided with a terminal 13 and a corresponding terminal 1 lis electrically connected to the primary winding of the coil. The coil 5 assembled on the body positions the terminals 13 and ill in the conductor sleeves 8 of the terminals 9. Thus it will be seen that the electrical connections between the coil and breaker assembly of the distributor are housed'and protected. against moisture or atmospheric conditions, also providing extremely short electrical connecall tions between said parts.

Offset portions 15 are formed on the body and terminate in angularly disposed and vertically arranged cup-shaped terminal sockets 16 provided with restricted throats s5 17. Electrodes 18 are embedded in the oil'- set portions 15 with their inner ends extend ing into the body in close proximity to the path of movement of the rotor 3 while the outer ends of the electrodes terminate witln in the sockets 16 so that when high tension 1 conductors 19 are inserted in said sockets as shown in Figure 5, the outer ends of the electrodes become embedded therein. The restrictedthroats 17 frictionally grip the insulation of said conductors and retain them in the sockets,-thereby establishing an efficient electrical connection between the conductors and the electrodes and one in which moisture will be excluded from. Spark lugs 20 are formed with sockets 21 simiar 1n construction to the sockets 16 to receive the other end of the hi tension conductors which also form moi re-proof connections between said conductors and the s ark plugs. The electrodes of the spark p ugs embed in the conductors similar to the electrodes 18.

While we have shown and described the 1. preferred embodiment of our invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of our invention, 15 as claimed.

Having thus described our invention, what we claim is i 1. In a device of the character described includin a distributor base having a breaker assem 1y electrically connected to an electrical source and a rotor, an insulated body mounted on said distributor head with a moisture-proof connection therewith and having1 the rotor operable therein, electrodes carrie by the body to receive electrical current from the rotor and electrically connected to spark plugs, a coil closing the body and having a moisture-proof connection therewith, an electrical connection between the coil and the rotor and confined in the body, detachable connections carried by the body with one of said connections connecting the coil to the breaker assembly and the ot er connection connecting the coil to a a ground, said connections bein confined within the body and housed an protected from moisture thereby.

2. In a device of the character described includin a distributor base having a breaker assem 1y electrically connected to an electrical source and a rotor, a body mounted on the base and receiving the rotor, extensions on said bod and having angularly related cup-shaped portions forming terminal sockets, electrodes embedded in said extensions and extendin from the sockets to the interior of the botfy to receive electrical current from the rotor, said sockets having restricted throats, high tension conductors received in said sockets and grip d b the throats with the electrodes embed d ed t erein, said conductors connected to spark lugs, a coil closing said body, and electr'ca ,connections between the coil rotor and the breaker assembly. 4

In testimony whereof we 'aflix our signatures.
